Reactive Oxygen Species, Antioxidant Agents, and DNA Damage in ...
2020年5月19日 · Here, we focus on changes in ROS and antioxidant agents under normal, non-stressful growth conditions and show that the ROS levels increase in whole cells and in plastids and mitochondria during maize leaf development.
Maize roots and shoots show distinct profiles of oxidative stress …
2020年3月1日 · Heavy metal accumulation in agricultural land causes crop production losses worldwide. Metal homeostasis within cells is tightly regulated. However, homeostasis breakdown leads to accumulation of reactive oxygen species (ROS). Overall plant fitness under stressful environment is determined by coordination between roots and shoots.
Reactive Oxygen Species in the Elongation Zone of Maize Leaves …
ROS release along the leaf blade was evaluated by embedding intact seedlings in 2′,7′-dichlorofluorescein-containing agar and examining the distribution of 2′,7′-dichlorofluorescein fluorescence along leaf 4, which was exposed by removing the …
Effects of potassium deficiency on photosynthesis, chloroplast ...
2019年2月1日 · Potassium (K) deficiency significantly decreases photosynthesis due to leaf chlorosis induced by accumulation of reactive oxygen species (ROS). But, the physiological mechanism for adjusting antioxidative defense system to protect leaf function in maize ( …
Iron redistribution induces oxidative burst and resistance in maize ...
2022年7月22日 · ΔClnps6 induced iron redistribution in maize B73 leaf cells and resulted in reactive oxygen species (ROS) burst to enhance plant resistance against Cu
Reactive Oxygen Species in the Elongation Zone of Maize Leaves …
2002年8月1日 · The production and role of reactive oxygen species (ROS) in the expanding zone of maize (Zea mays) leaf blades were investigated. ROS release along the leaf blade was evaluated by embedding intact seedlings in 2′,7′-dichlorofluorescein-containing agar and examining the distribution of 2′,7′-dichlorofluorescein fluorescence along leaf 4 ...
Water stress‐induced abscisic acid accumulation triggers the …
2002年12月1日 · In a recent study, the results indicated that water‐stress‐induced ABA accumulation was affected neither by ROS scavengers, tested with dimethyl sulphoxide (DMSO) and melatonin, nor by the direct treatment with O 2 – or H 2 O 2 in excised maize leaf and root tissues (Jia and Zhang, 2000).
Antioxidant Responses in Chromium-Stressed Maize as Influenced …
6 天之前 · Maize (Zea mays L.) faces significant challenges to its growth and productivity from heavy metal stress, particularly Chromium (Cr) stress, which induces reactive oxygen species (ROS) generation ...
Physiological Impact of Reactive Oxygen Species on Leaf
Specifically, it has been reported in maize under saline conditions that a decrease in ROS causes retarded leaf growth rather than increase in ROS levels (Rodríguez et al. 2004). Besides, abiotic stresses like salinity or drought accelerate the antioxidant capacity of the maize leaf, and hence limit cell expansion (Bernstein et al. 2010 ...
The symphony of maize signaling quartet defending against gray leaf …
2024年3月14日 · Zhong et al. found that ZmRBOH4, one of the six RBOHs in maize, was highly expressed and induced by pathogens in leaves. The ZmRBOH4 knocked-out lines exhibited compromised C. zeina-induced ROS levels and were susceptible to GLS, paralleling the vulnerability observed in Zmwik null mutants (Zhong et …
